Quark Pharmaceuticals Announces Dosing of the First Patient in Phase I/II Clinical Trial for Systemically Delivered siRNA Drug Candidate for Delayed Graf...(ly there is no marketed treatment for DG...),Health

The investigational drug candidate QPI-1002 is a siRNA designed to temporarily inhibit the expression of the pro-apoptotic gene, p53. This siRNA is based on Quark's proprietary, patented therapeutic concept of temporarily inhibiting the expression of p53 to protect normal cells from acute injury. QPI-1002 is a chemically modified siRNA discovered by Quark with structure covered under licenses from Silence Therapeutics and from Alnylam Pharmaceuticals. QPI-1002 was the first systemically administered siRNA in a human clinical study.
